Product details

Description

The LM2743 is a high-speed, N-Channel synchronous buck regulator controller with a 2%, 0.6V feedback reference voltage intended to make down conversion from 3.3V to as low as 0.6V easy.

Features

make power supply tracking and sequencing easy. The LM2743 employs output under-voltage and over-voltage flag, and current limit. Current limit is achieved by monitoring the voltage drop across the on resistance of the low-side MOSFET. The adaptive non-overlapping MOSFET gate drivers help avoid potential shoot-through problems while maintaining high efficiency. Both high-side and low-side MOSFETs are the lower cost N-Channel type, and the IC can accept a bootstrap structure to saturate the high-.
